Severe aortic stenosis due to a bicuspid aortic valve (BAV) is uncommon, especially in individuals under 65 years of age. While there are usually no significant differences according to the type of valve when it comes to surgery, with transcatheter aortic valve replacement (TAVR) some may arise. TAVR has seen significant advancements in the treatment...
TAVR has been shown beneficial, especially in high risk or inoperable patients. However, there are limitations to its use, especially with self-expanding valves, which are the need for pacemaker implantation and ECG changes after procedure. To address this matter, researchers assessed the right and left cusp overlap effect on 254 patients undergoing TAVR with self-expanding...
The use of ultravascular ultrasound (IVUS) to guide coronary angioplasty procedures (PCI) has been shown to reduce the risk of major adverse events in numerous randomized controlled studies, registries and meta-analysis. The current guidelines recommend the use of IVUS in left main disease and complex lesions. The proportion of complex PCI procedures has increased over...
Chronic coronary syndrome (CCS) has been considered another comorbidity in previous studies, and there has been no significant reduction in cardiovascular mortality or myocardial infarction (MI) rates with revascularization through percutaneous coronary intervention (PCI) or myocardial revascularization surgery (MRS) compared with optimal medical treatment (OMT). One possible reason for the lack of benefit has been...
Chronic total occlusions (CTOs) account for approximately 15-20% of patients with stable coronary artery disease. This field has seen various advances regarding treatment, leading to an improvement in the success rate of procedures. According to registries and randomized studies, the main indication for percutaneous coronary intervention (PCI) of CTO should be based more on clinical...
Aortic stenosis (AS) is a common condition that shares risk factors with coronary artery disease. Many patients can suffer from both diseases simultaneously, something that increases the risk of acute myocardial infarction in the presence of aortic stenosis. AS can cause ischemia even in the absence of coronary artery disease, due to ventricular hypertrophy, increased...
TAVR has been shown beneficial in patients across the risk spectrum. The PARTNER 2 SAPIEN 3 (P2S3i) study on intermediate risk patients was the first to show TAVR superiority vs SAVR when using the transfemoral approach. SAVR durability has been shown in different analysis but, except for a few reports, TAVR durability at long term...
Mitral regurgitation is the most common valvular heart disease. Its cause is most frequently functional or secondary dysfunction (functional mitral regurgitation, FMR) compared with degenerative mitral regurgitation (DMR), which is associated with decreased ventricular function, hospitalization for heart failure, and mortality. While medical treatment is effective over extended periods, a significant number of patients cannot...
Use of drug-coated balloons vs. drug-eluting stents in small caliber vessels. The constant advancements in coronary device technology have significantly reduced complication rates (such as that of restenosis). However, there are gaps where a high number of undesirable events prevail, such as small vessel disease (SVD), for which, in previous studies up, the rate of...
The rise of chronic total occlusions (CTO) percutaneous coronary interventions (PCI) goes hand in hand with technological development, through still posing a great challenge, one not exactly exempt from complications. An important criterion to successful CTO PCI is length: ≥20 mm lesions lower the odds, according to J-CTO Score. However, increasing operator experience and the...
